GEARING.

SPECIFICATION forming part of Letters Patent No. 721,149, dated February24, 1903.

Application filed October 29. 1901. Serial No. 80,427. (No model.)

in gearing, and more particularly to an im'- proved gearing forwashing-machines,ch urns, and the like, the object of the inventionbeing to provide a simple and efficient arrangement and construction ofgears to alternately rotate a driven shaft in opposite directions bymeans of a drive-gear rotated continuously in eitherdirection.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation, partly insection, illustrating my improvements; and Fig. 2 is a view in sectionon the line 00 w of Fig. 1.

1 represents the body of a washing-machine or churn, as the case may be,having the lid 0 or cover 2, on which is secured a metal frame 3.The-frame 3 comprises a base 4, secured to the lid by any approved meansand having an arched bracket 5, from one side of whichoutwardly-projecting and integral arms 6 are provided and converge to anintegral bearing 7, alining with a bearing in bracket 5 to support thedrive-shaft 8, driven by any desired means. On the end of drive-shaft 8which projects into frame 3 a gear-wheel 9 0 is secured and meshes witha circular rack or series of teeth 10 on an outwardly-projecting flangeat the periphery of a horizontallydisposed wheel'll, having a centralhub or bearing 12, connected to the wheel proper by an integral spider14:. This hub or bearing is mounted on a vertical shaft 14, supported insuitable hearings in bracket 6 and base 4 and projects down below thespider'13 and is made with an integral mutilated or segmental gear 15,for a purpose which will here- My invention relates to an improvementinafter appear, and a sleeve 16 is preferably mounted on shaft 14 belowgear 15 to assist in supporting the Wheel 11.

The dasher rod or shaft 16, on which may be sccured,in body 1, a dasherof any desired construction, projects up through base 4 and has securedthereon double integral gears 17 and 18, the formeror upper gear beingof appreciably smaller diameter than the lower gear 18 and adapted tomesh with the segmental gear 15 and be driven thereby in one direction,and the other or lower gear 18 meshes intermittingly with an internalmutilated or segmental gear 19 on the wheel 11 to drive this gear in theopposite direction.

The operation of my improvements is as follows: The drive-shafts isturned in either direction, thus turning gear wheel 9 and transmittingmotion to wheel 11 by means of rack or gear teeth 10 to rotate the wheeland the integral gear 15 continuously in either direction. The teeth ofthe segmental gears 15 and 19 are disposed directly opposite to eachother, so that when the segmental gear 15 engages gear 17 to revolvedasher rod 16 in one direction the segmental gear-teeth 19 are out ofengagement with gear 18, and as soon as the segmental gear 15 turns farenough to free itself from gear 17 the segmental gear 19 will engage thegear 18 and drive the dasher-rod in the reverse direction. Thus thesegmental gears 15 and 19 will alternately engage the integral or doublegears 17 18 to drive the dasher-rod in reverse direction.

It will be readily understood that by making the gear 17 the samerelative size to gear 15 that gear 18 is to gear 19 the speed anddistance of rotation of the dasher-rod can be made approximately thesame in both direction-s.

Various slight changes might be made in the general form and arrangementof the several parts described without departing from the spirit andscope of my invention, and hence I would have it understood that I donot 'wish to limit myself to the precise details set forth, but considermyself at liberty to make such slight changes and alterations as fairlyfall within the spirit and scope of my invention.

ICO

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination with a driven shaft and gearing fixed thereto, of acircular, casting having a continuous annular engaging face and providedwith two segments spaced apart, said segments disposed to successivelyengage the gearing on the driven shaft,adriving-shaft and a gear on thedriving-shaft in constant engagement with the continuous engagingsurface of the casting.

2. The combination with a frame and an arm projecting laterallytherefrom, of a wheel mounted horizontally in said frame and having acontinuous toothed periphery, said JOHN R. CARTER.
